Depth Anything ONNX

Open Neural Network Exchange (ONNX) compatible implementation of Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data and Depth Anything V2. Supports PyTorch 2 Export via TorchDynamo.

Monocular Depth Estimation with Depth Anything V2

Changelog:

🔥 ONNX Export & Inference

We provide a simple command-line tool dynamo.py based on Typer to export Depth Anything V2 to ONNX and PyTorch2 programs. Please install the requirements first.

$ python dynamo.py --help

 Usage: dynamo.py [OPTIONS] COMMAND [ARGS]...                            

 Depth-Anything Dynamo CLI                                               

╭─ Commands ───────────────────────────────────────────────╮
│ export   Export Depth-Anything V2 using TS or Dynamo.    │

If you would like to try out inference right away, you can download ONNX models that have already been exported here.

We observe the following average latencies using the CUDA Execution Provider:

Device Encoder Input Shape Average Latency (ms)
RTX4080 12GB ViT-S (1, 3, 518, 518) 13.3
RTX4080 12GB ViT-B (1, 3, 518, 518) 29.3
RTX4080 12GB ViT-L (1, 3, 518, 518) 83.2

Relevant framework versions:

CUDA==12.1
cuDNN==8.9.2
onnxruntime-gpu==1.18.0
torch==2.3.1

Export Example

[!TIP] You can view the available options at any time by passing --help.

python dynamo.py export --encoder vitb --output weights/vitb.onnx --opset 17

For dynamic shapes:

python dynamo.py export --encoder vitb -b 0 -h 0 -w 0

Export via TorchDynamo Example

[!CAUTION] The TorchDynamo-based ONNX Exporter is a new beta feature that may undergo breaking changes in the future. Currently, only static shapes and opset version 18 are supported.

python dynamo.py export --encoder vitb --output weights/vitb.onnx --use-dynamo -h 1036 -w 1036

Inference Example

python dynamo.py infer weights/vitb.onnx -i assets/sacre_coeur1.jpg

This function serves as an implementation reference for performing inference with only ONNXRuntime and OpenCV as dependencies.

Legacy

V1 ## 🔥 ONNX Export Prior to exporting the ONNX models, please install the [requirements](/requirements.txt). To convert the Depth Anything models to ONNX, run [`export.py`](/export.py). The pretrained weights will be downloaded automatically.
Export Example 
python export.py --model s
If you would like to try out inference right away, you can download ONNX models that have already been exported [here](https://github.com/fabio-sim/Depth-Anything-ONNX/releases). ## ⚡ ONNX Inference With ONNX models in hand, one can perform inference on Python using ONNX Runtime. See [`infer.py`](/infer.py).
Inference Example 
python infer.py --img assets/DSC_0410.JPG --model weights/depth_anything_vits14.onnx --viz
## ⏱️ Inference Time Comparison

Latency Comparison We report the inference time, or latency, of only the model; that is, the time taken for preprocessing, postprocessing, or copying data between the host & device is not measured. The average inference time is defined as the median over all samples in the [MegaDepth](https://arxiv.org/abs/1804.00607) test dataset. We use the data provided by [LoFTR](https://arxiv.org/abs/2104.00680) [here](https://github.com/zju3dv/LoFTR/blob/master/docs/TRAINING.md) - a total of 806 images. Each image is resized such that its size is 518x518 before being fed into the model. The inference time is then measured for all model variants (S, B, L). See [eval.py](/eval.py) for the measurement code. All experiments are conducted on an i9-12900HX CPU and RTX4080 12GB GPU with `CUDA==11.8.1`, `torch==2.1.2`, and `onnxruntime==1.16.3`. ### Notes - Currently, the inference speed is bottlenecked by Conv operations. - ONNXRuntime performs slightly (20-25%) faster for the ViT-L model variant.
